Improved process control of the hot strip mill may lead to indirect energy savings through reduced product rejects, improved productivity, and reduced down time. The primary aim is to control the oxygen level, and hence optimize the combustion in the furnace, especially as the load of the furnace may vary over time. The savings depend on the load factor of the furnace …

Heater effectively maintains a hot-working temperature, the primary processing factor affecting grain size of steel and the resultant key mechanical characteristics of the end product: strength, hardness, and ductility. In a typical hot strip mill, steel slabs are overheated to ensure that edges remain hot enough for final processing.
